Beginning with Plato and Aristotle, philosophers throughout history have built their theories around the problem of reconciling a fundamental distinction, as for example, Plato's distinction between knowledge (reality) and opinion (appearance), Descarte's mind/body distinction, and Kant's a priori/a posteriori distinction. This 'problem of difference' is a classic theme in philosophy, and one that has taken especially intriguing turns in recent decades. Jeffrey A. Bell here presents a finely constructed survey of the contemporary continental philosophers, focusing on how they have dealt with the problem of difference.
